A constant temperature metal bath is a precision temperature control instrument that utilizes microcomputer control and semiconductor cooling technology. It offers high temperature control accuracy and excellent sample processing parallelism, making it widely applicable for preserving samples for various analytical instruments, storing enzymes and facilitating enzymatic reactions, denaturing nucleic acids and proteins, pre-denaturation for electrophoresis, PCR reactions, serum coagulation, and aging tests for various product materials.
Compared to traditional constant temperature devices, the semiconductor-based constant temperature metal bath overcomes drawbacks such as significant temperature fluctuations, susceptibility to contamination, and cumbersome temperature control. It serves as an excellent alternative to conventional water baths, eliminating issues like heating contamination. Furthermore, the device provides more precise temperature control and a wider temperature control range.
The temperature control module of the semiconductor constant temperature metal bath employs semiconductor cooling technology, which offers the following advantages:
High-Precision Temperature Control: The semiconductor cooling module achieves a constant temperature precision within ±0.1°C, meeting stringent requirements for high-accuracy temperature management.
Rapid Response: The semiconductor cooling system features a short response time, enabling temperature to quickly decrease or increase to the set point. This enhances flexibility in temperature control protocols.
High Performance and Vibration-Free Operation: Unlike traditional compressor-based cooling, the semiconductor cooling system contains no moving mechanical parts. This results in high system reliability, extended service life, and elimination of adverse effects on instruments caused by vibration.
Compact Design: Semiconductor cooling technology allows for the design of very compact cooling systems, facilitating the miniaturization and reduced weight of the constant temperature bath apparatus.
Safety and Environmental Friendliness: The semiconductor cooling system requires no refrigerants or cooling water, minimizing contamination risks and offering a more environmentally friendly and safer solution.
